In 2012, a newly formed patent assertion entity (PAE) called Black
Hills Media filed a suit against us for alleged infringement of 11
patents they had acquired from defunct companies. Despite Black
Hills Media being a PAE (which are sometimes labeled as “patent
trolls”), we thoroughly investigated the patents before deciding
our course of action. Not only were we 100% certain that we did
not infringe any of these patents, but we also strongly believed
the patents themselves were not valid.
We chose to fight back in court and at the Patent Office. We
spent millions of dollars and thousands of hours defending our
position, on the principle that you should not pay for something
you do not use.
Good for Sonos.
